Structures
The structure maintains the shape of things under the
force of gravity, the force of wind, etc...
-
For example, humans have a skeleton, bicycles have a
frame, houses have columns...
Types of structures
-
-
A bycicle frame supports the load that it carries on the seat. The elements in the bicycle’s frame are the aluminium tubes; the unions are the aluminium
-
-
Types of unions
Permanent unions: These are structures that we don't need to dissamble. Examples: weldings, glue,rivets...
No-n permanent unions: with non-permanent unions we can assemble and dissemble the elements of the structure. Examples: nuts and bolts, clamps, friction...

Mass structures
Shell structures
Shell dules They are made of a thin outer layer of material around a volume. They keep the shape and supports the load
-
-
semicircular arch, is the most common. The stone at the very top is called 'Keystone'. It own weight is the main load.
-
often, we combine different types of structures into a more
complex structure.For example, houses have brick walls (mass structures), columns
and beams (elements of a frame structure), etc.
-
they are made of a thin layer around a volume. The volume can be empty or contain something with no structural relevance.
-
-
A suspension structure holds an element by cables that are held from the top of a tall column. The space between one column and the next is called the ''span''.
-
Structural elements
-
The column is another element, united to the foundation and to the primary beams.
-
-
Applications
The design of the structure of an object helps reduce the amount of material used. This reduces the price and the weight and improves safety.
